this is normally only needed on new rims and lugs.. so they will seat properly after teh first 50miles.. once they have seated, then it shouldnt be needed... however swithin up rims may cause them to need a retorque i guess. i dont know i never have to switch up to winter beater down here in florida... sticks tongue out! LOL anyway thanks for the reminder.. i actually never even bust out the torque wrench, i just tighten them down and add a little bit of my 240lb self down on the handle a little bit.. usually good enough for me, sometime they are a little hard to get off though, especially the rears.. is that bad, and whats teh normal torque range? 100lbs?
